The Gradall Company Salaried Employees'
Savings and Investment Plan
New Philadelphia, OH  44663

                          INDEPENDENT AUDITOR'S REPORT

We have audited the accompanying statements of net assets available for benefits
of The Gradall Company Salaried Employees' Savings and Investment Plan as of
December 31, 2002 and 2001, and the related statement of changes in net assets
available for benefits for the year ended December 31, 2002. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of The Gradall
Company Salaried Employees' Savings and Investment Plan as of December 31, 2002
and 2001 and the changes in net assets available for benefits for the year ended
December 31, 2002 in conformity with accounting principles generally accepted in
the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of Assets Held
for Investment Purposes at the End of Year is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental information is the responsibility of the
Plan's management. The supplemental information has been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

NOTE 1: PLAN DESCRIPTION

     The following brief description of The Gradall Company Salaried Employees'
     Savings and Investment Plan (the "Plan") is provided for general
     information purposes only. Participants should refer to the Plan document
     for more complete information.

     Organization

     The Plan was established effective January 1, 1987 and is a defined
     contribution plan covering all eligible salaried employees of The Gradall
     Company (the "Company"). The purpose of the Plan is to provide retirement
     and other benefits to eligible employees. The Plan is subject to the
     provisions of the Employee Retirement Income Security Act of 1974
     ("ERISA").

     Administration

     The Plan is administered by the Administrative Committee (the "Committee")
     of JLG Industries, Inc. ("JLG"). The Company is a subsidiary of JLG. The
     Committee interprets the Plan document, establishes procedures to implement
     provisions of the Plan, approves benefit payments due participants, and
     authorizes other disbursements from the Plan. The Committee has engaged
     Massachusetts Mutual Life Insurance Company as custodian (the "Custodian")
     for the Plan assets.

     Participation

     Salary employees are eligible to participate in the Plan on the first day
     of the month that coincides with or immediately follows the date on which
     the employee completes 83 hours of service. Upon enrollment in the Plan, a
     participant may direct employee and employer contributions in any of
     thirteen investment options, including JLG common stock.

     Participants may change their investment options at any time, via telephone
     or Internet.

     Participant Loans

     Participants may borrow from their fund accounts a minimum of $1,000 up to
     a maximum equal to the lesser of $50,000 or 50% of their account balance.
     Loan transactions are treated as a transfer to (from) the investment fund
     from (to) the loan fund. Loan terms range from 1-5 years (longer if loan is
     being used to purchase a principal residence). The loans are secured by the
     balance in the participant's account and bear interest at a rate
     commensurate with local prevailing rates as determined quarterly by the
     Committee. Interest rates are based on prime plus one percent. Principal
     and interest are paid ratably through monthly payroll deductions.

     Contributions

     The Plan provides for contributions by employees through salary reductions
     only. The Plan also provides for a discretionary contribution as determined
     by the Company. During 2002 and 2001, the Company elected to make
     contributions for the eligible employees of The Gradall Orrville Company.
     The amount of the contributions was based on the number of hours worked by
     each employee. The Company has made no other discretionary contributions to
     the Plan for 2002 or 2001.


                                                                          PAGE 5

                               AND INVESTMENT PLAN

                          NOTES TO FINANCIAL STATEMENTS


NOTE 1: PLAN DESCRIPTION (Continued)

     Each participating employee elects to enter into a written salary reduction
     agreement with the Company, thereby contributing to his or her salary
     reduction account a whole percentage of compensation per payroll period,
     not to exceed 20% of the participant's compensation as defined in the Plan.

     Distributions

     Participants' accounts are payable upon attaining age 59 1/2 and election
     by the participant or age 70 1/2 with or without an election by the
     participant, termination of employment, retirement due to permanent
     physical disability, or at death. The Plan allows a participant to apply
     any portion of any contributions made to the participant's account toward
     the purchase of whole life insurance policies which designate the trustees
     as the owners of the policies; however, the policies are for the sole
     benefit of the participant or his/her beneficiary. The cash surrender value
     of these policies is excluded from plan assets. A non-hardship withdrawal
     of the participant's salary reduction account is also allowed upon
     attainment of age 59 1/2 by filing a written request with the plan
     administrator at least thirty days prior to the proposed withdrawal date.
     The Plan also provides for the withdrawal, less any earned interest, of the
     participant's salary reduction account or the vested portion of his/her
     employer account in certain hardship situations.

     Participant Accounts

     Each participant's account is credited with the participant's
     contributions, the Company's contribution, and an allocation of Plan
     earnings. Allocations are based on participant earnings, hours worked, or
     account balances, as defined. The benefit to which a participant is
     entitled is the benefit that can be provided from the participant's vested
     account.

     Vesting

     Participants are immediately 100% vested in their contributions, the
     Company's contributions and earnings.

NOTE 2: SUMMARY OF ACCOUNTING PRINCIPLES

     The financial statements have been prepared in conformity with accounting
     principles generally accepted in the United States.

     Basis of Accounting

     The accompanying financial statements have been prepared on the accrual
     basis of accounting.

     Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires the Committee to make estimates and
     assumptions that affect certain reported amounts and disclosures.
     Accordingly, actual results may differ from those estimates.

                                                                          PAGE 6

NOTE 2: SUMMARY OF ACCOUNTING PRINCIPLES (Continued)

     Investment Valuation

     The Plan's investments are stated at fair value. Shares of mutual funds are
     valued at quoted market prices which represent the net asset value of
     shares held by the Plan at year end. Participant notes receivable are
     valued at cost which approximates fair value.

     Administrative Costs

     The Company may pay all or part of the out of pocket administrative
     expenses of the Plan.

     Reclassifications

     Amounts previously shown have been reclassified to conform to current year
     presentation.

NOTE 3: INVESTMENTS

     The following presents investments that represent 5% or more of the Plan's
     net assets.

NOTE 4: TAX STATUS

     The Plan obtained its latest determination letter on June 5, 1995, in which
     the Internal Revenue Service stated that the Plan, as then designed, was in
     compliance with the applicable requirements of the Internal Revenue Code.
     The Plan has been amended since receiving the determination letter.
     However, the Committee believes that the Plan is currently designed and
     being operated in compliance with the applicable requirements of the
     Internal Revenue Code. Therefore, no provision for income taxes has been
     included in the Plan's financial statements.

NOTE 5: TERMINATION OF THE PLAN

     The Company intends to continue the Plan indefinitely; however, the Company
     reserves the right to reduce, suspend or discontinue contributions to the
     Plan or to terminate the Plan at any time by vote of its Board of
     Directors. Timing of distribution of Plan assets would be determined by the
     Company's Board of Directors.
